Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481388, here are decompositions:

19 + 33481369 = 33481388
37 + 33481351 = 33481388
67 + 33481321 = 33481388
79 + 33481309 = 33481388
97 + 33481291 = 33481388
229 + 33481159 = 33481388
271 + 33481117 = 33481388
307 + 33481081 = 33481388

Showing the first eight; more decompositions exist.
